Sum of all amount if charge dates are the same in Stripe

Question

I\'m iterating over a stripe charge object and I want to sum up the amount total for each day.

# Returns an array object of charges for a customer

You'll need to iterate through each charge object in Stripe, storing the amount and the parsed date for each charge:

# Fetch charges in batches of 100 records from Stripe API, yield each individual charge to a block.
def each_stripe_charge_for_customer(customer_id)
  starting_after = nil
  loop do
    customer_charges = Stripe::Charge.all(customer: customer_id, limit: 100, starting_after: starting_after)
    break if customer_charges.none?
    charges.each do |charge|
      yield charge
    end
    starting_after = charges.data.last.id
  end
end

charges_by_date = Hash.new(0)

# For each Stripe charge, store the date and amount into a hash.
each_stripe_charge_for_customer(current_user.stripeid) do |stripe_charge|
  # Parses Stripe's timestamp to a Ruby date object. `to_date` converts a DateTime object to a date (daily resolution).
  charge_date = Time.at(stripe_charge.created).to_date
  charge_amount = stripe_charge.amount

  charges_by_date[charge_date] += charge_amount
end
